For the ""race of truth"" you need to have the best blend of efficient equipment and an efficient position properly set-up for YOU. Wind tunnel-inspired designs have their appeal but the man-machine couple needs to work in perfect harmony to optimize performance. The best rider, on a poorly fitting bike, will not perform to his or her top potential. The best way to realize YOUR cycling goals is through a custom-designed triathlon and time trial frame. The race of truth demands it.

Seat angles: There is much debate in the cycling world about seat angles and their impact on efficiencies, performance, and aerodynamic positioning. The best science shows that the human body performs optimally (from a physiological standpoint) at seat angles between 72 and 75 degrees. The variation in angles is truly a function of inseam measurements and the related length of the lower limb components. In basic terms, longer legs have longer femurs (upper leg) which requires placement farther behind the bottom bracket than shorter legs. The bio-mechanic efficiencies as well as anatomical constraints make this a requirement. The knee's relation to the bottom bracket should be regarded in the same fashion as weight-lifting. For instance, anyone who has had instruction on doing squats or lunges has been told that the knee should never go beyond the foot when performing those activities. The resulting stress on the joint can lead to significant injury. The same concept applies to the bike.

Seat angles do receive incremental changes based on the type of cycling being done but the respect for the repetitive use and joint function must be maintained. For example, a 10 mile time trial with a 78 degree seat angle may not have any adverse physiological effect doing it one time. But, longer repeated efforts would conspire to unduly stress the articulations, not to mention aid the onset of other adverse physiological conditions (myalgias, poor pedal stroke coordination, etc).

The best approach to time trial and triathlon fit is to ignore what you see elsewhere on the road and focus on your individual proportions, fitness level, and body type. What may be advantageous from an aerodynamic view may have a greater negative impact from a physiological and/or health standpoint. Our BalancePoint™ ensures that you are considered as a complete system, with the full impact of training, competing, and bike handling characteristics applied.

Many pundits point to the success of riders who use the far-forward position to prove their points. One needs to simply consider those who perform even more successfully with very relaxed set-ups to see that no one rule can be applied across the board. It's 100% personalized, which makes a custom frame all the more important. Consider too that two of cycling's greatest against -the-clock performers had these values in their time trial positions:

-EDDY MERCKX

1969: Tour de France TT Créteil -Paris

  • Seat Angle: 72°
  • Head Angle: 71.5°
  • Saddle to bar height difference: 4cm

-MIGUEL INDURAIN

1992 : Tour de France TT Luxembourg-Luxembourg

  • Seat Angle: 71°
  • Head Angle: 71.5°
  • Saddle to aero pad height difference: 1cm

Frame design:

The proper rider position is key. Any good frame design proceeds from this principle. A rider is going to be on the frame and it won't just sit in a wind-tunnel dazzling the aerodynamic experts and getting some good numbers. That is too impractical.

The bike needs to fit your position.You should't have to confirm to the position the bike dictates. Many riders are lucky enough to fit stock geometries. If not, consider a custom frame. The investment and the corresponding increases in performance and comfort are worthwhile. A frame that fits the rider, allowing him to exploit the proper physiological function is correct. The frame (and resulting bike) should handle correctly, allow for proper weight distribution, and cause no constraints to the rider's function on the machine.

For time trial and triathlon frames we favor angles that respect this principle. Time trial means an all-out 100% effort for the rider. Stability in aero bars, handling on technical courses, and the ability to go ""a bloc"" is the point. Aerodynamics is important but not to the detriment of the rider, his position, and the performance of the frame in real-life riding. We hold true to this. In triathlon, we respect the running leg to follow the bike portion. The aggressive position found on a time trial frame will be tempered, as the triathlete isn't going all-out, needs to maintain some reserves, and is looking for some increases in energetic efficiencies that a rider going all-out for a time trial doesn't need to consider as much.

All KGS / Cyfac Nerv DS2 custom bicycles have unlimited options for finish and paint options. Email, call or Skype (kevingsaunders) us with your ideas and we can turn them into reality.

Positioning:

KGS / Cyfac Custom Triathlon or TT Bicycle CAD All KGS Custom Bicycles are designed around your true bicycle position. Our proprietary BalancePoint™ Positioning System is only available in San Antonio, in person. Once we know exactly where the saddle and handlebars are to be located, we draw the entire bicycle in CAD and the frame drawing is sent to Parlee for fabrication. When the frame is completed, we can then build the bike to the drawing and it is perfect.
